Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Methyl-1-phenylpyrazolo[3,4-d][1,3]oxazin-4(1H)-one.
6-Methyl-1-phenylpyrazolo[3,4-d][1,3]oxazin-4(1H)-one (CAS 51649-70-8) is a high-purity analytical reference standard with the molecular formula C12H9N3O2 and a molecular weight of 227.22 g/mol.
The molecular framework of 6-Methyl-1-phenylpyrazolo[3,4-d][1,3]oxazin-4(1H)-one (C12H9N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
